LoopUp

What LoopUp does

LoopUp is a UK-headquartered cloud communications provider that delivers Microsoft Teams telephony services to multinational enterprises across more than 100 countries. Founded in 2003 and listed on AIM in 2016 (subsequently delisted), the company has executed a strategic pivot away from legacy audio conferencing toward consolidating enterprise PSTN replacement onto the Microsoft Teams platform. Its core product suite includes Operator Connect (Microsoft-certified SBC-less connectivity), Direct Routing as a Service (DRaaS), Bring Your Own Carrier (BYOC), and SIP Trunking, all administered through a unified global management portal called LoopUp One.

The underlying technology leverages a private global IP/MPLS voice network with peerings to 20 tier-1 regional carriers for QoS-optimized routing. LoopUp holds Microsoft Solutions Partner status with Advanced Specialization in Calling for Microsoft Teams and is the top-ranked Operator Connect provider per Microsoft. The company operates six offices across the UK, US, Australia, Hong Kong, and historically Barbados, with localized sales presence in Germany, France, Spain, Sweden, Australia/NZ, and both Traditional and Simplified Chinese markets.

LoopUp generates revenue through recurring subscription-based telephony services priced per user/number, supplemented by professional services for design, deployment, and onboarding. The go-to-market is direct enterprise field sales targeting large multinational IT and finance decision-makers, with quote-based pricing tailored to geographic footprint and volume. The customer base is concentrated in enterprise multinationals across manufacturing, commercial real estate, staffing/recruitment, and consumer goods, with named logos including Thyssenkrupp, Avison Young, Allegis Group, and PUMA. The company is led by co-CEOs and co-founders Steve Flavell and Michael Hughes.

Broad incumbents

• BT Global Services: BT is a major global carrier offering Teams-integrated telephony through Operator Connect and Direct Routing, competing for the same multinational enterprise consolidation mandates that LoopUp targets, with deeper owned network infrastructure.
• Vodafone Business: Vodafone Business delivers global UC, SIP, and Teams telephony services to multinationals. As a top-tier Operator Connect provider with its own carrier network across Europe, Africa, and Asia, it is a direct competitor for LoopUp's multinational consolidation deals.
• Verizon Business: Verizon offers Teams Calling via Operator Connect and broader managed communications for global enterprises. Its combination of owned network assets and large enterprise sales force makes it a key incumbent competitor to LoopUp in North American and EMEA multinational accounts.
• Orange Business: Orange Business provides global Teams telephony, SIP trunking, and unified communications to multinationals across EMEA, APAC, and the Americas. Its owned carrier footprint and global enterprise relationships compete directly with LoopUp's consolidation pitch.
• Vonage (Ericsson): Vonage, now part of Ericsson, offers cloud communications APIs and UCaaS, including Teams integrations for enterprise customers. It represents a larger, API-led alternative competing for cloud telephony and collaboration budgets.
• Sinch: Sinch is a cloud communications provider offering voice, messaging, and SIP trunking to enterprises globally. Its enterprise voice and SIP offerings overlap with LoopUp's SIP Trunking and PSTN replacement products.

Direct peers

• 8x8: 8x8 is a cloud UCaaS and CCaaS provider that integrates with Microsoft Teams and targets mid-market and enterprise customers globally. It competes with LoopUp for Microsoft-aligned enterprise telephony and broader unified communications budgets.
• RingCentral: RingCentral is a leading cloud communications platform offering voice, UC, and contact center, with Teams integration capabilities. It is a comparable cloud-native alternative for enterprises evaluating Microsoft-centric telephony consolidation.
• IntelePeer: IntelePeer is a cloud communications provider offering Teams-certified Operator Connect and Direct Routing services, with automation and AI features layered on top. It is a direct niche competitor targeting similar mid-market and enterprise UC customers.

Emerging players

• Alianza: Alianza provides cloud-based communications platforms for service providers and enterprises, including Teams Calling support. As a smaller cloud-native player, it competes in overlapping Microsoft-aligned telephony niches.
